Unlike the general-purpose IOS found in many branch routers, was built from the ground up for the data center. Its primary focus is resiliency and modularity . Key features that define its "next-generation" status include:
Cisco Nexus switches, powered by NX-OS, offer a range of features that make them an ideal choice for next-generation data center architectures. Some of the key features include: Unlike the general-purpose IOS found in many branch
To ensure rapid recovery, NX-OS uses PSS to store operational runtime information, allowing services to restore their last known state instantly upon restart. Some of the key features include: To ensure
Modern enterprises have data centers in three clouds and two on-prem sites. NX-OS bridges this gap. : vPC eliminates the need for Spanning Tree
: vPC eliminates the need for Spanning Tree Protocol (STP) by allowing links physically connected to two different Cisco Nexus switches to appear as a single Port Channel to a third device. This enables active-active redundancy and full bandwidth utilization. Powering the Modern Architecture: VXLAN and EVPN
For true "Next-Gen" automation, Cisco introduced ACI. This is a software-defined networking (SDN) policy model where the network is defined by the needs of the Application rather than the underlying switch configuration.
